ah yeah HP did issue a recall for the dv6000 motherboard
but the recall has expired supposedly (it was a 24month recall)
so looks like u're sol you can try contacting HP to see if they'll fix it anyway but HP forums is filled with people who didnt get theirs fixed because it was out of the recall period
there was a recall for the battery pack as well, that got extended to 2011 but expired @ the end of May
and your lappy may be using an Nvidia chip that was part of some lawsuit settlement (faulty nvidia chip + hp using crappy thermal tape)
http://www.nvidiasettlement.com/ unfortunately, as it would seem, the period for getting a repair/claim through this settlement has also ended earlier this year (march for claim and july to submit)
time for a new laptop :/
